I've bought and sold a lot of used guns and I haven't had any problems that stick out in my mind.

I've owned three Kahrs, still own two, and am the original owner of one of them. Only had one dealing with Kahr customer service and it was handled perfectly.

When you say in your post that you "bought a 500 smith once, I was the 4th owner. The cylinder locked up and the crane was damaged. I sent the gun back and had it back in a week with everything replaced for free"......you had to know it was broken when you bought it. Then you say you have more examples of this.

Are you buying these used guns, knowing that they have a problem...then hoping to have the company warranty sort them out? Or are you paying full price for a gun that is supposed to be working fine and you are getting ripped off by some pos seller?

If this is the latter, why not take your anger out on the guy that sold that sold you these lemons?
